Does anyone know what changes that was done in the update to the TFI-IV Intermittent Analyzer (Rotunda 007-00035) for the Computer Controlled Dwell update for 1994 and newer trucks?

If so do you have a diagram of the wiring changes that were made?

From the Ford shop manual:
TFI-IV Intermittent Analyzer (Rotunda 007-00035). Necessary for diagnosis of intermittent distributor ignition system faults. Step-by-step diagnostic procedures included. The TFI-IV Intermittent Analyzer can not be used with ICMs that have Computer Controlled Dwell (CCD) unless a CCD update has been added to the analyzer or a TFI-IV Intermittent Analyzer (Rotunda 007-00035) which has a CCD compatible label on the tester is used.
